摘要:
The invention relates to a tool for the outside milling or for the rotary broaching of tools that rotate about the longitudinal axis thereof during machining. A disk-shaped tool carrier includes peripherally arranged cutting inserts or cartridges having cutting inserts. According to the invention, the cutting inserts or the cartridges are arranged on a ring-shaped or partially ring-shaped, segment-shaped carrier that is removably fastened to a machine spindle either directly or indirectly by an adapter.

The invention relates to a tool for turning/turn broaching or external milling of work pieces rotating about longitudinal axes during machining, comprising a disc-shaped tool support having cassettes (20) disposed peripherally thereon, each of said cassettes containing a cutting insert (12, 13, 14), said cassettes being fastenable to a circular, partially circular or segmented removable support (11) that is fastened either directly to a machine spindle or indirectly to a machine spindle by way of an adapter. According to the invention, the cassette (20) comprises a plate seat with a seating surface (21) and two lateral surfaces (22, 23) as contact surfaces for the cutting insert (12, 13, 14) and can be radially adjusted by way of an adjustment member (27) and can be fastened by way of a clamping member (18); the cassette (20) further comprises a slit-shaped groove (30) parallel to the seating surface (21) for the cutting insert (12, 13, 14), said groove having opposing groove walls with a distance and angle with respect to one another that are adjustable by way of an adjustment screw (33) such that the angular position of the seating surface (20) can be changed.

The invention relates to a cutting insert for clamping into a disc-type or strip-shaped tool body, in particular, for milling crankshafts, whereby the insert is substantially cuboid-shaped and has two front faces, two side faces, serving as cutting faces as well as an upper and a lower side face, whereby a convex face is arranged between the front faces and the upper and lower side faces, so that the upper and lower side faces and the convex face form cutting edges each with a side face. According to invention, the cutting insert has an inwardly-tapered face adjoining the convex face, which allows the cutting edge to protrude and tapered chamfers are provided between the inwardly-tapered faces of the front face on both sides of a planar supporting surface to the outer edge.

The invention relates to a cutter support (11) for fastening to a cutter head, comprising a shaft-like pin (11) and a head, having a soldered-in cutter (12) with a minor cutting edge formed by a face (27) and a free surface (28). According to the invention the minor cutting edge has a rounded area (25), the radius of which continuously increases from a minor cutting edge end (25a) at least to the cutting edge center, or to the other minor cutting edge end (25b).

The invention relates to a cutter support for fixing in a cutter head, comprising a shaft-like bar and a head with integrated cutters with minor cutters formed from a cutting surface and a free surface. According to the invention, a chamfer adjacent to the minor cutter is arranged on the free surface with a chamfer width decreasing outwardly to 0.

The invention concerns a cutting insert (10) for drilling. Said cutting insert (10) has a substantially rhomboid basic shape and its four cutting edges (20, 30), which each form cutting corners (15, 16), are broken, two first opposite cutting edges (20) each having cutting edge sections (21, 22) which form an obtuse angle (&egr;1) of between 140 and 180° and 230° are produced. The invention further concerns a drill, wherein at least two of said cutting inserts are disposed on the front face of the shank, each disposed in a recess. The radially outer cutting insert has a concave active cutting edge and the radially inner cutting insert has a convex active cutting edge.
